This statement by Mihawk is one of the most astute and important in the entire manga. As far back as Arlong Park Luffy himself was saying how dependent he was on his crew. Marineford takes that idea and magnifies it tenfold--literally every chapter where Luffy has significant screen time, he is saved by someone else.
We joke about the Power of Friendship™, but the series is chock-full of examples of people helping Luffy and Luffy helping people in turn, and this unnatural charisma being the literal superpower that will lead him to achieve his dreams.
